Aki has long flowing purple-colored hair and distinct red eyes. She also wears pink lipstick and small gold pearl-shaped earrings.

Though she is often seen dressed in her Tokken uniform while on duty for the Tokken agency, Aki dons a red top and somewhat rugged brown jacket over a dark green skirt and purple heels in her free time. In this outfit she also wears a brown bag and a small gold necklace with a pendant around her neck.
